Banco de Dados: Nativo x Open Source

Banco de Dados:Biblioteca Nativa

Criando uma tabela CRUDdb.execSQL(“CREATE TABLE IF NOT EXISTS Category (

id INTEGER PRIMARY KEY, name TEXT

);”);

// Selectdb.execSQL(“SELECT * FROM Category;");

// Insertdb.execSQL("INSERT INTO CategoryValues (‘xyz’);");

// Updatedb.execSQL(“UPDATE Category SET name = “abc” WHERE id = 1;");

// Deletedb.execSQL(“DELETE FROM CategoryWHERE id = 1;");

Banco de Dados:ActiveAndroid

Criando uma tabela CRUD@Table(name = "Categories")public class Category extends Model {

@Column(name = "Name")public String name;

}

// Selectnew Select()

.from(Category.class)

.execute();

// Insert & Updatecategory.save();

// Deletecategory.delete();

Banco de Dados:Sugar ORM

public class Category extendsSugarRecord<Category> {

public String name;}

// SelectSelect

.list();

Iremos usar os seguintes componentes open source:

Sugar ORM

http://github.com/satyan/sugar

NiftyDialogEffects

http://github.com/sd6352051/NiftyDialogEffects

AndroidSwipeLayout

http://github.com/daimajia/AndroidSwipeLayout

FloatingActionButton

http://github.com/makovkastar/FloatingActionButton

FloatingLabelWidgets

http://github.com/marvinlabs/android-floatinglabel-widgets

Let’s Code!

1º - Configurar o Projeto

1. Baixar o projeto

http://bit.do/s-task

2. Abrir no Android Studio

2º - Entender o Projeto

AndroidManifest.xmlContém a declaração das Activities

TasksActivityActivity da tela principal, exibe a lista de tarefas

TaskEditActivityActivity da tela de criação e edição das tarefas

TaskAdapterAdapter responsável por criar as linhas da lista

TaskModelo que representa uma tarefa e a tabela no banco de dados

res/layout/Contém as interfaces gráficas das Activities

build.gradle (Module: app)Arquivo de configuração do aplicativo

3º - Configurar app/build.gradle

apply plugin: 'com.android.application'

android {compileSdkVersion 22buildToolsVersion "22.0.1"...

}

dependencies {compile fileTree(dir: 'libs', include: ['*.jar'])compile 'com.android.support:appcompat-v7:22.0.0'compile 'com.nineoldandroids:library:2.4.0'compile 'com.github.satyan:sugar:1.3.1@aar'compile

'com.github.sd6352051.niftydialogeffects:niftydialogeffects:1.0.0'compile "com.daimajia.swipelayout:library:1.2.0@aar"compile 'com.melnykov:floatingactionbutton:1.3.0@aar'compile 'com.marvinlabs:android-floatinglabel-widgets:1.6.1@aar'

}

4º - Criar ListView em

activity_tasks.xml

<ListViewandroid:id="@android:id/list"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/white"android:divider="@color/accent"android:dividerHeight="0.25dp"/>

5º - Implementar

FloatingActionButton em

activity_tasks.xml

<com.melnykov.fab.FloatingActionButtonandroid:id="@+id/fab"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="bottom|right"android:layout_margin="16dp"android:src="@drawable/ic_add"app:fab_colorNormal="@color/primary” />

6º - Implementar

FloatingLabelEditText em

activity_task_edit.xml

<com.marvinlabs.widget.floatinglabel.edittext.FloatingLabelEditText

android:id="@+id/title"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_margin="10dp"app:flw_inputWidgetTextSize="22sp"app:flw_labelTextSize="18sp"app:flw_labelText="@string/title" />

7º - Implementar Sugar ORM

Task TasksActivity

private void saveTask(){task.title = “...";task.description = “...";task.save();

}

private void loadTasks(){tasks = Select

.from(Task.class)

.orderBy("id DESC")

.list();}

public void deleteTask(Task task){task.delete();tasks.remove(task);tasksAdapter.notifyDataSetChanged();

}

public class Task extends SugarRecord<Task> {public String title;public String description;public boolean done;

public Task(){

}}

TaskEditActivity

8º - Implementar TaskAdapter e

SwipeLayout em TasksActivity

private void loadTasks(){...if(!tasks.isEmpty()){

tasksAdapter = new TaskAdapter(this, tasks);tasksList.setAdapter(tasksAdapter);

}}

public void toggleTaskStatus(Task task, ViewstatusView){

if(task.done){task.done = false;statusView.setBackgroundColor(getResources()

.getColor(R.color.gray));} else {

task.done = true;statusView.setBackgroundColor(getResources()

.getColor(R.color.accent));}task.save();

}

9º - Implementar NiftyDialog em

TasksActivity

public void showTask(final Task task){final NiftyDialogBuilder dialog =

NiftyDialogBuilder.getInstance(this);dialog.withTitle(task.title)

.withMessage(task.description)

.withDialogColor(getResources().getColor(R.color.primary))

.withEffect(Effectstype.SlideBottom)

.withDuration(300)

.withButton1Text(getString(R.string.close)).setButton1Click(new

View.OnClickListener() {@Overridepublic void onClick(View v) {

dialog.hide();}

}).show();

}
